The height limit of the underpass is 16 feet, what is the inequality?

Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.

But these things will change direction of the inequality: ...

Don't multiply or divide by a variable (unless you know it is always positive or always negative)
